Plotting the run rate in this chart shows Square’s sexy growth curve — it actually seems to be accelerating a bit. (Not precise, because it’s based on PR opportunities and not necessarily internal milestones, but it should be close-ish.) Reaching $15 million per day — er, $5.5 billion per year — should happen this summer, and Square might even double its current rate this year.

Watching this company continues to be very exciting.

Perhaps this is just a general overview but, looking at Dan's chart, Square's evident rise is truly impressive.
